- To all whom it may concern:

Be it known that I, EM-IL R. OREcELIUs, a citizen of the United States,residing at Providence, in the county of Providence an the pivot pinagainst longitudinal play.

Heretofore the fulcruming means in this class of pins have consisted ofindependent pieces which after some use become detached; or an inwardlyfolded finger which crimps the stock of the pin in bending and inpractice forms an uncertain and non uniform caring for the pin tonguehead.

ated, my invention consists in thenovel construction and combinationofparts hereinafter set forth, and illustrated in the accompanyingdrawings, wherein Figure 1 is a plan view of the pin blank. Fig.2, aplan elevation of the same after the first operation. Fig. 3, a sectionon line 3, 3 of Fig. 2. Figs.4 and 5, sections on lines 4, 4 and 5, 5respectively of Fig. 3. Fig. 6, a plan of the pin after the secondoperation.

Like reference letters indicate like parts throughout the views.

My pin is formed as follows: A blank or planchet is cut from a sheet ofmetal, shaped as shown in Fig. 1, comprising a body, a, lateral ears,1), adjacent one end, and a lateral projection, 0, adjacent the otherend. By suitable dies the blank is struck into the form shown in Fig. 2,consisting of an oblong, cupped body, a, with upwardly inclined blankears, 6, and projection, c. The

incomplete pin is next subjected to the action of compression dies andpunches, whereby thematerial in the walls of the body near and at theirends is compressed, forming solid integral bearing or fulcrum blocks, dand d, in opposite ends of the body, 0,, whose top surfaces arepreferably slightly inclined towards the center of the pin body. Theaction of the punches is to form cavities, e, in ears, d. The edge ofthe cup walls are by the tools referred to rounded as at f, to avoidcutting edges and give a finished appearance to that part of the body.The parts as described are shown in Figs. 6, 7, 8 and 9. The pin is completed by bending the projection, c, to form a catch and bending theears upwardly, so that the cavities, e, shall receive the ends of the.pivot pin, g, upon which is mounted the pin tongue, h, the forwardportion, is, of whose head, Z, bears'down upon the integral block, (1.The pivot pin is incapable of any slipping v or longitudinal movement inthe ears, and T o the end of securing the advantages and avoidlng thedisadvantages above enumer-.
